Google Buzz - The Gmail social networking

Google has announced on Tuesday that it is immediately rolling out Google Buzz, a location-aware social networking tool highly integrated with its Gmail client, Google Maps and a new Android app.

Available as a new tab in the standard Gmail interface, the service will share links, Gmail status updates, YouTube videos and Picasa photos. Other users can leave comments on your shared data as you can to theirs: users to share Buzz can be automatically added from your contacts, suggested by Google through frequency of correspondence, or selected individually. Buzz updates can be sent to Twitter, but as yet there is no automatic importation of tweets.
Start conversations about the things you find interesting. Share updates, photos, videos, and more.
